Why is bragging called "bragging"? Are there any allusions in history?

Since ancient times, people have called those unrealistic and daydreaming's behaviors "bragging" to describe those exaggerated and boastful behaviors and practices. Cowhide is tough, and it takes some difficulty to blow it up, just like something that can never be done. You have to brag to others that you can do it, and lie to them that you have done a good job and no one else knows. This is called "bragging". When it comes to the origin of this word, the specific time is very vague, and it was passed down from generation to generation before it became popular today.

As long as any word is meaningful, there must be a corresponding explanation. There are many versions of the story about "bragging" in history, of which two are the most widely circulated. In a village before, there was a child who felt good about himself. He likes to talk big every day and live in unrealistic imagination. At first, when he boasted to others, someone believed him and paid him a lot of attention. Gradually, people found that the children were lying to them. Most of what he said is not true, which wastes their feelings. Therefore, no matter what the child says in the future, people will no longer believe him. One day, several hungry wolves came to the village. When the children saw it, they shouted in horror and fled for help, but no one wanted to open the door for him. Finally, the child tasted the evil consequences of bragging all day and became dinner in the hungry wolf's stomach.

The second story happened in another village. At the head of the village, there are several gambling grandfathers who get together to play cards and gamble almost every day. At first, they just gambled on small things, and this loss was nothing to them. After a long time, they are no longer satisfied with the pleasure of betting on small things, and start betting on houses, cars and even their beloved women. Many people say it's unreasonable and don't care. However, their promises have not been fulfilled and their words have not been fulfilled. Finally, he was spurned by the villagers and abandoned by his family. They were homeless and starved to death on the road.
